Moya- IMPROVEMENT IN CARDvG-RINDER.

The` Schedule referred to in these Letters Patent and making part of the same I, JOSEPH STANDRING DRoNsFlnLD, of' Oldham, iu the county of Lancaster, in the Kingdom of Great Britain, have invented certain Improvements in Apparatus for Grinding Cards employed in the preparation of cotton and other fibrous materials, of which the following is a specification.

Natal-rc and Objects of the I )went/ion.

My invention ,relates to the vmachines employed to grind the cards or the card-rollers employed in carding-engines, and consists, in the first place, in support-ing the roller which is to be ground in or upon two arms or bearers, which are fixed to a shaft mounted in bearings formed on or attached to the frarnngof the machine.

To the said shaft is fixed a lever, and a pin, carried bya worm-wheel, workingin a slot formed in the said lever, so that when the worm-wheel is rotated, the card-roller will be caused .to approach the grindingroller,ror to recede therefrom. f

A fan, which is fitted to the machine, removes the dust.

A second portion of my invention consists in the combination and arrangement of the parts forming the complete machine.

Description of the Accompanying Drawings.

Figure 1 is a front elevation, and

Figure 2, an end elevation of -the 'machine as represented by the model.

Figure 3 is a front elevation of a complete machine, represented as operating on a card-roller, and

Figure 4 is an end elevation of the same.

The machine is shown wit-h a breakin its width, as the said Width may be varied to suit different lengths of' rollers.

Figure 5 is an enlarged detached view of the aforesaid worm-wheel and slotted lever.'

General Description.

Referring to the said figures, and moreparticularly to figs. 3 and-4- f a a are the end frames of the machine, which are connected together by cross-rails b b.

The driving-shaft c revolves in bearings formed in or attached to the end frames, and is fitted with fast and loose pulleys (I, by means of which it is actuated, and with the pulley e, which drives the grinding-roller f, and also with the pulleys q g, which drive the cardroller.

The grinding-roller f is covered with emery or other suitable I natenal, as is usual, and is fitted with the curved guardsmasings, or covers-h h, which are hinged together and inclose the grinding-roller, with Athe exception of a space at the front sufficient for the application and working of' the card-roller.

I A portion of one end of the card-roller is shown at Ii, in fig. 3, and in end view in fig.- 4.

The end `journals of the card-roller rest in bearings formed in the upper ends of the arms k It', the said bearings heilig either of the V-form, as shown, or of any other suitable form.

The said arms are fixed to the shaft l, which is mounted in the bearings m m, fixed to the cross-har 11', and on the said shaft is also fixed the slotted lever fn, (see fig. 5,) the 'slot of which lever is entered bythe piu o, fixed to the worm-wheel p.

The said worm-Wheel is mounted on astud carried by the bracket q, and is operated by the worm r.

XVhen the said Worin is rotated by means `of the hand-wheel s, the pin o operates on thel lever a, and causes the shaft l to turn in its bearingsiu either direction, according to the'directiou in which the hand wheel is turned, and thus the card-roller, after being placed in its bearings, may be vbrought into contact with the grinding-roller, and may he fed toward the said roller as it is being ground, and may then he withdrawn, the parallelism of the card-roller and the grinding-roller being at all times maintained.

The space within the casing h h is connect-ed by the side pipes t with the casing of the fan fu.. This fan is driven by the band-wheel c, fixed on the shaft c, throughan intermediate pair of band-wheels,

w w, in order toincrease the speed of' thel fan. v

The Afan removes the dust and particles-of grit which may be discharged into the outeratmosphere through a suitable pipe or case, so that the machine may be worked in the carding-room, instead of in a special room, as is usual.

rlhe method of driving the fun may be varied, as, for example, the fan maybe driven direct from one of' the journals of the grinding-roller.

The card-roller, not being a portion of the machine, does not appear in the model.

C' laifms.

I claim, as my invention- 1. 'lhe combination of the arms k k, the shaft c, the lever n, and the worm and wheel r and p, substantially as and for the purpose hereinbefore set forth. 2. lhe combination of' the said arms, shaft, lever, worm, and worm-wheel with the fan and with the other parts of` the machine, forming-the complete cardgrinding machine, substantially as hereinbefore 4set forth and as shown in figs. 1 and 2 of the drawings.
